I'd recommend to you "Guidelines for Laboratory Design," 4th edition, by LJ DiBerardinis, JS Baum (and others). It's very good and very practical.

As to number of fume hoods - it would depend on the type of curriculum proposed. In a new building, we installed 14 fume hoods in a single lab to accommodate organic chemistry teaching. 2 students share a 6 foot hood with two hoods for dispensing and waste collection. We limit out at 24 students per section, too.

I think this requirement comes from the fire code but it's important to remember 50 sq ft per student is required in the lab. That translates to about a 1200 sq ft lab for each 24-student section. We are mostly compliant with that requirement - within 10% or so.

Prudent Practices is also a great resource.

Subject: [DCHAS-L] Undergraduate instructional lab guidelines

Fellow DCHAS-L members:

My college is in the process of designing and planning new labs which will be used for undergraduate general and organic chemistry. We are in need of guidelines, specifically with respect to number and nature of fume hoods in a 24-student lab.

Is there a Web site where authoritative information on this subject can be found?

Thank you.
